What does all of this 1080i mean please i dont understand?

Answer 1

Basically, if you split the tv up into rows and columns, there would be 1,080 rows on the tv and about 1400 or so columns. The important thing is the rows. Standard televisions have 480 rows and they are "refreshed" every other line. Basically at any given point in time, a regular TV is displaying 240 rows. and a moment later, the other 240 rows in an interlaced fashion. High definitions have the ability to display 720 rows that are all there at any given point in time (720p) or 1,080 rows that are again refreshed in the interlaced fashion (1080i). There is also 1080p which is a shame that they did it this way since old HD sets do not support it, meaning even an HDTV won't necessarily be the best HD in a couple of years. Transition phases for technology are always a big headache! A perfect example is the transition from standard definition video to high definition. And the transition from DVD to one of the competing high-definition formats. It's a good thing that they are happening at the same time though.

Answer 2

There are currently two standards in HD broadcasting which are 1080i and 720 (or40) p. The i stands for interlacing and the p for progressive. When refreshing a picture interlacing refreshes simultaneously the vertical and horizontal whilst progressive goes along the horizontal line by line. 1080i is obviously slower than the 700 range and so it is used where a maximum definition but no speed is required. Few tellies can do 1080i. The 700 range is used where action is fast (athletics, action films etc).

Answer 3

In 4th grade terms:

Take regular photographs..you have wallet size, and 4 x 6 & 5 & 7 and 8 & 10...and so on. compared to HD terms

the bigger the number, the better the picture.

Answer 4

its the resolution of the tv.

more pixels.

some tv's are 720 and others are 1080.

the higher it is the better/clearer/sharper the picture will look
